This page aggregates measured, corroborated evidence: donors' iPhones recorded apps contacting this domain, every claim below was reported by separate accepted donations and published under a human verdict (later rows for an approved app inherit its verdict). A contact is a measurement, not an accusation — it does not show what data was sent.

What our research panel found AI-drafted · human-reviewed
We ask several independent AI models the same question and publish their answers separately — cross-vendor agreement is evidence against fabrication, and disagreement is worth seeing. 3 of 3 models answered, overall confidence medium — classification split: anthropic=unknown, openai=unknown, gemini=first-party. A human reviewed this domain's claims before anything here published.
Anthropic Claude — unknown
The hostname pattern (a 'speedtest' subdomain under sbcglobal.net, historically an AT&T-associated domain) is consistent with an ISP-hosted Ookla measurement endpoint used for the app's core speed-test function rather than a tracking, analytics, or ad endpoint, but I cannot verify current ownership or role, so I classify it as unknown. Nothing in the provided evidence shows a data flow beyond the measurement traffic inherent to running a speed test, so I do not mark it undisclosed.
OpenAI — unknown
The domain appears related to an AT&T/SBCGlobal-hosted Speedtest endpoint, but ownership and its precise function are not provided. The contact alone does not establish a data flow that contradicts the empty privacy label.
Google Gemini — first-party
The domain belongs to AT&T (SBC Global) and serves as a hosted speed test server used to measure network performance, which is core first-party functionality for the Speedtest app.
